Serial No. 239,584.

This invention relates to improvements in sashand frame constructionsand morepan ticularly to a construction whicheliminates the necessityof'usin'g latches for securing the sash in adjusted position and tofaconstrucadvantageous features and refinements. j L s lhile theoonstruetionaboutfto be disclosed is adaptable -iior use in variousdiiferent ways it finds particular utility in connection with buses andthe like. In motor vehicles-such' as buses `difficulty is* eXperie'ncedin Afitting the sashes to the frames because of the variances in thedistance between the frame members.

If a standard or'uniform size sash-isem'ployed as is the custom it islfound that in some instances the sash llits the rame'member -tootightly and in other instancestoo loosely so that on the wholethefitting of sashesft'o the iframes is 5 "difficult, 'expensive andotherwise unsatisfactory. Furthermore because ofthe weaving of theirameof the vehicle inuse and by reason offotherdistortion ofthe sash frames,di'iculty is frequently eX'peiienced'in vraising andlowerihgthe sash.Many of the heretofore known forms `of sash havealso been found -to be{objectionablebecase the construction necessitated'the use "Oflatches orthe like to hold `the sash-infadj'u'sted position. v i t is thereforeone 'of theprimary objects of this invention topiovide'a latchless sashand frame construction which may-'be read-ily assembled irrespective ofvariations inthe distance between the jframe membersV or the dimensionsof the "sash `and l'which' 5may be 'readily raised and loweredwithoutliability 'of the same binding. VIn'a`ccomplishing this I provideaframe, the side members oi which have their inner walls for portionsthereof transversely oppositely inclinedv thns 4providing ay taperingopening o'rf recei-vmgthel Resilient means is associated withYtlnefsa'sh' normally urg'ing'the sash transversely ot the l framemembers toward the converging'edges of the inclined walls. Notchedmembers are associated with the iframe' members y'adjacent' theconvergingedgesoff lthe inclined walls, the sash'being urged intolengagementwith these notched yrr'iembers bythe resilient means wherein:Y VFigurel is an elevational view "of'a `sash Vraised or lowered andwhen releasedthe resilient means again urges thesashl transverselytoward the converging edges of the inclined side walls and intointimateengagement with these side walls and also into engagement withthe notched members. By reason oi the tapering character oi the frameVopening sashes of Vvarying width may be accurately iitted within theiramefand 'variance in the distance between the frame members is also ofno consequence.

The several objects, advantages and novel details of construction ofthis invention will be made more apparent as this description proceeds,especially when considered in connection Awith the accompanying drawingsandv frame constructed inV accordance `with this invention.

Figure 2 is a vertical sectional view Vtaken substantially on the planeindicated by line 2-r-2 in Figure 1.

Figure 3 is'an enlargeddetail sectional view' taken substantially onthe'plane indiv lcated'by line 3-3 in Figure 1.

V Figure 4 is a similar sectionalview taken substantially on the planeindicated by line 4 4 in Figure 1, and y Figure `is a detailsectionalview showing :1n-application of the invention to a `metal busconstruction.

Referring now to the drawings and more especially to Figures 1 to4inclusive it will ybe f noted that there is illustrated a frame VIVwhichconsists essentially of a pair of spaced side members 10,- asill-rl-lrand aheader 12. A'sash is slidably mountedV in the frame andconsists ofa top member 13a bottom member V14 and av pair otside members15.

The members 13, 14 and 15 of which the sash is compos'ed'may beoi anydesired form or construc- Ytion lbut are ormed'with channels or meansproviding a channel by means of which the glass 16 is secured in place.rlhe lower sash member lll is formed with a channel or recess 17 inwhich a tubular compressible weatherstrip 18 is secured which in theclosed position of the sash is adapted to engage the sill 1l toweatherproof the sash at the lower edge thereof.

The upper sash member 13 is formed with return-bent portions or tongues19 engaging in grooves or recesses in a weatherstrip 2O whichweather-strip is formed with a laterally projecting lip or extension 21adapted for engagement with a surface or wall formed interiorly of theheaderl 12. This surface 22 is inclined with respect to the path oftravel of the sash and as the sash approaches its closed position lip 21engages surface and thus weatherproofs the sash at the upper edgethereof.

1n the construction shown in Figures l to 4 the pillars or side framemembers l0 are illustrated as of wooden construction, and in such casesit has been found to be desirable to associate or secure to the innerface of each pillar 10 a plate or face member 23 which in effect becomesa paie of *he side frame members. This plate member is bent to provide atransversely inclined portion 24 and a laterally extending llangeportion 25 constituting aportion of the sash guide. The other edge ofeach plate member is bent to provide a member 2G which is notchedlongitudinally thereof as indicated at 27. lillhile the notched member2G is here shown as formed integrally with plate member 23 and whilethis is a convenient form of construction nevertheless these notchedmembers may be constructed separately and secured to the side framemembers in any desired manner.

'lhe side sash members l5 are each formed with a portion or surface 28adapted for engagement with the inclined walls 2d of the pillars orframe members. As shown this portion of the sash members is curved orarcuate in cross section and from an examination of Figure l it will benoted that the sash members l5 are recessed to accommodate and receiveweatherstrips 29. Y

Means is provided for resilient-ly urging' the sash transversely of theframe into engagement with the inclined walls of the latter and towardthe converging edges thereof or in other words toward the narrowerportion of the frame. 'Vhile any desiredform of resilient means may beemployed there is illustrated herein coil springs 30 located within theside sash members l5 which act upon plungers 3l slidablymounted in thesash members. These plungers 31.en gage the flange member 25 and thusurge the sash member transversely of the frame and into .engagement withthe inclined walls thereof. rlfhe side sash members may each be formedwith a laterally extending lip or flange 32 which acts as a cover flangeand cooperates with the flanges 25 carried by the frame members toconcealthe plungers 3l and to protect the same.

rlhe lower sash member is provided with a tongue or projection 33 whichmay be formed separately and secured thereto or may illustrated hereinbe formed of an integral part of the lower sash member lll. rlliistongue or lip 33 is 'adapted for engagement with the notched members 2Gfor securing the sash in any of its adjusted positions.

It will be obvious that the sash may be easily raised and lowered bygripping handle members 34 and moving the sash transversely against theaction of the spring pressed plungers 31 toward the diverging edges ofthe inclined side walls of the frame or in other words between thoseportions of the side frame which are spaced wider apart. This will giveample clearance between the sash and frame to permit the sash to bereadily raised or lowered and if the sash has been raised when the sameis released the spring pressed members will urge the same transverselyof the frame and cause the lip 33 to engage in the adjacent pair ofnotches 27. lWhen the sash is in its lowermost or closed position thelip 33 extends into the recess formed by cutting away the lower edge ofthe notched members as indicated at 35.

In Figure 5 there is illustrated an adaptation of this invention to allmetal construction wherein a pillar constituting one of the framemembers is indicated by the reference character 36 and as shown consistsof a member substantially T-shaped in cross section. Brackets or anchor`members 37 are secured to each pillar 36 at spaced intervals throughoutits length and a member indicated generally by the reference character38 is shown as entirely enclosing the pillar 36 and anchor 37. Thismember may be conveniently formed of sheet metal substantially ininverted U-shape in cross section. The base of the U is formed withshouldered portions 39 adapted for snap engagement with Athe head of theT-shaped pillar member. The member 38 is formed with laterally extendingflanges Ll0 constituting a portion of the sash guide and retainer plates41 are secured to the anchor members 37 the ends 42 of these membersconstituting flanges completing the guides for receiving the sash. Thatportion of the member 38 adjacent each flange 40 is shaped to provide aninclined wall 453 for cooperation with the sash as in the previouslydescribed form of` construction.

With a sash and vframe constructed in accordance with the presentinvention it will be obvious that sashes may be more readily fitted tothe frames without regard to variances in the distance between framemembers or in width of the sash. The tapering side walls of the frameand the spring pressed means for urging the, sash into enga-gementtherewith will under ordinary conditions provide sutlicient latitude topermit of a satisfactory fit between the sash and frame despite anyordinary variances in dimensions. Furthermore by reason of the fact thatthe sash may be moved laterally toward the diverging edges of theinclined side walls of the frame a sutlicient clearance between the sashand trame is always possible to thus enable the sash to be readilyraised and lowered. The spring pressed means normally urging the sashinto engagement with the walls of the frame will compensate for wearbetween the parts and prevent rattling. -Furthermore with the hereindescribed construction thev sash may be held in its adjusted positionwithout necessitating the use of a complicated latch mechanism.

Obvious changes Vin the details of construction and rearrangement ofparts may suggest themselves to those skilled in this art and to thisend reservation is made to make such changes as may come within thepurview of the accompanying claims.
